"He belongs here," Tina told Access Hollywood during an exclusive set visit to the NBC comedy, which returns for its fourth season on Thursday night. "I feel like it's imminent… I think he's making a movie or something, but if he wants to come sometime after that, we would love to have him. He's got mad skills."

While that may be in the cards for the show, after guest stars such as Oprah Winfrey, Jennifer Aniston and Jon Hamm joined "30 Rock" for Season 3, Tina said the fourth season will focus more on the cast.

"We'll see them more in their world, we may try to see some new colors on them, some new relationships," Tina said, revealing that "TGS," the show-within-a-show, will be picking up a new cast member.

"Alec [Baldwin]'s character has put it upon me to go and find someone who will appeal to the rest of America because Tracy [Morgan] and [Jane Krakowski] are such New York creeps, that they're trying to find someone normal to be in the cast… be more popular in the real America," she joked.
